Abstract
This paper presents a design of 12㎓ VCBRO(voltage controlled dielectric resonator oscillator) using a novel PBG(photonic band gap) ground plane and a varactor circuit that enhances the frequency linearity of VCO with different bias to varactors. The PBG structures are used for suppressing the second and third harmonics without any filters. To simulate the accurate resonating frequency, a DR coupled with microstrip lines is analysed by FTM(finite element method) simulation, and the results are transformed into scattering parameters to design the VCO. Some measured results are presented to show the usefulness of the proposed techniques.
